The SeatCushion by Tempur-Pedic™
Product Review (submitted on October 24, 2011):
I purchased this cushion with the lumbar support as I have degenerative spinal disease. Sitting on this cushion has relieved the sciatica pain that I was experiencing using just pillows. I use these cushions on my LazyBoy recliner and what a relief that I can sit for a movie and not feel horrid pain.
